I can tell you from experience that TDV6 engines can take up to 15-20 minutes to warm up. Whether it's a RRS or Discovery. Hence why I like petrol Land Rovers in Winter. [biggrin]
Hi Mk1_oz,
interesting topic for me at the moment, Thanks for starting the thread.
I'm in the (long) process of determining which D4 to buy. Something I discussed with my wife over the weekend was the topic relating to the cold climate pack. (I'll come full circle back to the intent of your original post shortly...) See we will eventually be living on the New England Hwy, just inside QLD, and up there is pretty cold. We also hope to spend some time in the high country over winter in the next few years. As such, and after trolling forums in Britain, we determined that the cold climate pack would be an option we would like as it will provide my wife comfort far sooner than the coolant-heated heater. Also, she is cold blooded and the heated steering wheel will provide her lasting comfort on cold days after dealing with our lovely tribe.
When we owned our D1 300TDI, we experienced the engine temp fall from operating temp to the low 70's a few times (had a block temp sensor installed). Reason being; when towing a camper trailer and using the engine as a brake, the diesel engine is just acting as a high volume, low pressure compressor (400psi is pretty low pressure compared to what we use at work), and if little to no throttle is applied, then the 'compressor' is just moving very large quantities of cool air. As such the engine cools down dramatically. That would be what you are experiencing.
To come back full circle to your original point;
When we buy our D4, we will be living SE of Melbourne. Because of the climate, and the short run to school, and the high wear on a cold engine, and my intent to use alternate fuels, and my desire for the car to be at operating temperature before my wife gets home after completing the school run on rainy crap weather days (5km round trip), I am considering options to pre-heat the D4.
This might be something you could consider too.
Just a thought,
Cheers,
Adam.
I went fishing with my brother once and went in his 2011 Hilux - I fell in the water and got cold and had to come home and I mentioned that it was a shame the heater would not work until we got home - he said not so and he was right. Apparently the Hilux has a system that on start the radiator is blocked off and all coolant is diverted to the heater matrix and when correct temp is reached the radiator comes online. It works and the Hilux did provide almost instantaneous heat.
Now I believe the D3/D4/RRS supposedly has a similar system but it certainly does not work as well as it does take a will to get heat through where in the Hilux is very quick. Though my RRS is certainly quicker in generating heat than my old Freelander diesel.
Now I have to say - the Hilux is a crap vehicle with a number of design issues related to its injectors and steering column - my brother's has been replaced a couple of times - but from cold its heater does work well.

Been rather fresh this week and when i drop my daughter off at school which is about 500-600m as the crow flies, i found the heater was warm as i dropped her off and by the time i reached the freeway (ring rd) 10mins later i had full heat.
